Abstract: An image sensor includes a substrate, a first pixel disposed in the substrate, the first pixel including a first photoelectric conversion region, a second pixel disposed adjacent to the first pixel in the substrate, the second pixel including a second photoelectric conversion region, a first floating diffusion region in the first pixel, a second floating diffusion region in the second pixel, an insulation layer on the substrate, and a first buried connect penetrating the insulation layer and connected to the first floating diffusion region and the second floating diffusion region, wherein the first buried connect includes an upper surface and a lower surface, the upper surface of the first buried connect is at a higher vertical level than an upper surface of the insulation layer, and the lower surface of the first buried connect is at a higher or equal vertical level than a lower surface of the insulation layer.

Abstract: An image sensor includes a first substrate including a focus pixel region and pixel regions around the focus pixel region, each of the focus pixel region and the pixel regions including at least one photoelectric conversion region, color filters provided on the focus pixel region and the pixel regions, respectively, and on a first surface of the first substrate, and micro lenses provided on the color filters, respectively. The micro lenses include an auto-focus lens on the focus pixel region, a first micro lens adjacent to the auto-focus lens, and a standard micro lens spaced apart from the auto-focus lens.
